摘　　要：通过相关文献的钢板剪力墙试验数据验证了使用等效拉杆模型并利用SAP2000有限元软件进行Pushover分析计算多层钢板剪力墙水平极限承载力方法的正确性。利用试验验证的有限元分析方法分别研究了4层单跨钢板剪力墙和4层3跨钢框架-钢板剪力墙双重抗侧力体系在倒三角型分布的水平荷载作用下剪力墙板高厚比的变化对结构水平极限承载力的影响,并与相应纯框架的结构性能进行了比较,建议剪力墙板的高厚比取为250~300,这为钢板剪力墙的设计提供了理论依据。The effectiveness of equivalent strip model calculating the horizontal ultimate bearing capacity of multi-story steel plate shear walls(SPSW)by using the software SAP2000 to make Pushover analysis was demonstrated by comparing the simulated values with results from experimental studies performed by different researchers.The effect of different slenderness ratios on the ultimate bearing capacity of four-story single-span SPSW and four-story three-span dual steel shear walls system subjected to the inverse tr...
